Bolting in Savoy Cabbage
Savoy cabbage features distinctive crinkled, deeply textured leaves and a mild, delicate flavor superior to smooth-leaved varieties. Bolting is when a plant prematurely produces a flower stalk and goes to seed, usually triggered by heat or day length. It makes herbs and leafy vegetables bitter and unusable.
